Specification of Letters Patent.

Patented Aug. 8, 11922.

To all whom it may concern." Y

Be it known that l, STAFFORDF. So'rnpn- LAND, a citizen of the United States, resldlng in the cit and county of Philadelphia and State of ennsylvania, have invented certain new and useful Improvements in Collapsible Folding Boxes, of which the followlng 1s a specification.

My invention relates to folding boxes and especially to that type known as collapsible boxes, and the object of my 1nvent1on is to provide an improved box of this character, that is simple in construction, inexpenslve of manufacture and can be very easily and very quickly set upthat is, erected in box form-and is securely held in erect positlon, after it is set up. I

The objects and advantages of my 1mproved box, will be readily apparent in this specification when taken in connection w th the accompanying drawings, in wh1ch-F1g.

' 1, is a blank of which the box-body is formed.

Fig. 2, is a locking-flap. Fig. 3, is a view of the complete box-body in its flat or collapsed form. Figs, 4 and 5 are views of an end section of the box-body showing two stages, in the operation of setting it up. Fig. 6,15 a view of the box-body fully setup. F 1g. 7, is a view of an end section of the box-body, fully set up, and has a part of the lockln flap torn away. Fig. 8, is a blank, of who the box-cover is formed. Fig. 9, is a view of the complete box cover, in its flat, or collapsed form. Fig. 10, is a View of an end section of the box-cover, set up. Fig. 11 is slightly modified. Fig. 11, is the blank (Fig. 1) with the locking-flaps to be attached. Fig. 11 is the staple (enlarged) used for attaching the locking-flap to the end-wall of the box. Flg.

12, is a view of the complete box-body. in its fiat form, and shows the locking-flap attached with staples. Fig. 13, is an end section of a modified form of the blank. Fig. 14, is an end section of this box (Fig. 13) in its fiat form. Fig. 15, is a single blank of which both the box-body and the box-cover are formed. Fig. 16, is a view of the complete box (Fig. 15) in its flat form. Fig. 17,

is a view of this box (Fig. 16) set up. Fig. I

18, is a viewof this box (Fig. 17) closed. Fig. 19, is the blank Fig. 15) slightly modified, of which both ody and cover of the box, are formed. Fig.20, is .a view of the complete box F i 19) in its flat form. Fig. 21, 1s a view of t is box (Fig. 20) set up.

Referring to the drawings; Fig. 1 is a blank of w ich the box-body is formed, and 1s a single piece of paper-board or other suitable material, and it is creased or scored at the dotted lines 2, longitudinally, at the dotted lines 3 transversely, and at the dotted lines 4 diagonally, so as to facilitate the bending or folding of its various parts at these lines, in forming the body; and this blank comprises the following foldable parts, namelythe bottom A, opposite side-walls B,. opposite end-walls C, and corner-folds D integral with and connectmg the side-wall and the end-walls and this corner-fold D comprises two triangular sections D and D In making this boxbody, the blank is folded longitudinally at the lines 2, the side-walls B folding on the bottom A and the corner-folds D on the end-walls C,-as shown in Fig. 3, and a sepa-- rate locking-flap F, shown in Fig. 2, is then placed on each end-wall C, over the cornerfolds, and is attached to the end-wall, by

sewing or stitching it to the wall, along the outer, or free edge 9 of the wall at the dotted line 8, as shown in Figs. 3, 4, 5, and 6; the sewing or stitching being done by a sewing-machine, the thread passing throu --h the outer edge of the triangular section 1 of the corner-fold and thus holding that section to the end-wall and allowing the other .triangular section D to.v fold freely under the locking-fie. and below the stitching, while the boxody is being set up. This will be more clearlyfunderstood by referring to F ig. 7, which is a view of an end section of the box-body, set up, and shows a portion of the locking-flap E torn away; and it will be seen that the triangular section D of the corner-fold is held to the endwall C by the stitching 8, but the upper edge 6 of the triangular section D is below the stitching and is therefore free to move back or forth under the locking-flap, asthe box is collapsed or set up. As the locking-flap extends very nearly to the bottom of the box, it therefore holds the box securely in erect position when it is set up, and when it contains goods, the goods will hold the flap against the wall and the box-body cannot collapse until the goods are taken out; also as-the locking-flap is cut out separately blank can therefore be cut out with no waste of material, whereas there will be, consider- I able waste of material if the flap is an ina -tegral part of the blank, cut out with the at 10, is a view of an end section of this boxblank; and moreover the locking-flap can be of a lighter, more flexible and cheaper material than the blank, and this will not only lessen the cost of the box, but will also permit the box to be set up more easily and more uickly. When the box in its flat form ig. 3,) has to'be set up, it is only necemary to grasp both end-walls and push them to an erect position, the side-walls moving automatically to an erect position also; or grasp both side-walls and pull them to an erect position, the end-walls moving automatically to an erect position also; but in -'either case the triangular section D of the corner-fold, will very easily and very uickly fold back against the other section and the locking-flap will very easily and very quickly move over this triangular section,-to' an erect position on the inner side of the end-wall and thus-securely hold the boxbody in its erect position. The very easy and very quick way in which the box may be set up, will be more fully understood by referring to Figs. 4 and 5, which are views of an end section of the box-body and show twostages in the operation of setting it up. In Fig. 6, the box-body is shown set up..

Fig. 8, is a blank of thebox-cover, and it is practically the same as that of the body blank (Fig. 1) but the'end-walls are deeper than the side-walls-the depth of the endwa'll' (J from the dotted line P to its baseis the depth of theside-wall B. This cover blank is folded longitudinally at the dotted lines 2, and the locking-flap. E is attached to the end-wall C by stitching it along the edge 9 of the wall at the dotted line 8, as

shown in Fig. 9, which is the complete box-cover in its flat form, and it is set up in the way I have already descrlbed. Fig.

cover, set up. The separate locking-flap E (Fig. 2) -may be attached to the end-wall by other means-than that of stitching it with a sewing machine; it ma be attached by hand or by a machine, stitc ing it tothe end-wall, along its outer or free edge 9, and

using-wire staples F, as shown in Fig. 12. A staple F (Fig. 11*) is used at each end- 10 of the flaps E near the outer edge 9 ofthe wall, and as many more staples F as may be necessary between these two end staples all along the edge of the wall. The lockingllap E may be wider and creased, scored, slit or folded at the dotted line 11 as shown in Fig. 11 and placed at the endsof the blank Fig. 11, (which is thesame as blank Fig.

with the narrow-part 12 on the end-wall raaapea part 13 of the locking-flap folded on the corner-folds and end-walhand attached to the wall with staples, along the edge 9 of the wall, as shown in Fig. 12. The ends of these old and well known staples pass through the parts and are bent and clinched on the other sidein the old and well known box-cover are formed. It is scored or creased at the dotted lines 14 longitudinally, at the dotted lines 15 transversely, and at the dotted lines 16 diagonally. It comprises the following foldable sections, namely-the body bottom H, the body sidewalls J, the body end-walls K and K the body corner folds L, the body corner-fla s M, the cover top N the cover side-walls the cover end-wall l and the cover cornerfolds R. The body corner-fold L comprises the triangular section L? and L and the cover corner-fold R comprises triangular sections R and .R Slots S are made in the bod side-walls. This blank is folded longitu inally at the dotted lines 14, the parts of the body, namely, side-walls J folding on the bottom H, corner-folds L on end-wall K and corner-flaps M on end wall K and the parts of the cover, namely, sidewalls '0 folding on the; top N and cornerfolds R on end-wall Pajand locking-flaps E (Fig. 2) are attached to the outer end-wall K of the box and the end-wall P of the cover as shown in Fig. 16, which is the complete box in its "fiat or'collapsed form. In this case the locking-flap is stitched to the end-wall by a sewing machine, along the outer edge of the wall, at the dotted line 8; but'it may be attached by means of staples as before described and shown in Fig. 12. This box is set up for use by simply pulling the side-walls of both body and cover, to an erect position and the other foldable .parts will automatically move to their proper set shown set up; and in Fig. 18, it is shown closed, with the free corners T of the sidewalls of the cover, inserted in the slots S of the side-walls of the body. The blank Fig. 19, is a slight modification of the blank Fig. 15. The only difference between the two blanks, is that in the Fig. 19 blank the corner-folds L are substituted for the corner-flaps M of the Fig. 15 blank; but in all neaaoee other respects they are both the same; and this blank (Fig. 19) is folded longitudinally at the dotted lines 15, the same as the other; but locking-flaps E are attached to both end-walls K and K of the body and also the end-wall P of the cover. The locking flaps are attached in the way before described and shown. Fig. 20 shows the complete box in its flat form, and it is set up in the way already described and shown. Fig. 21 shows this box, set up.
